AET CSCTELMBL Satin Chrome Classical Telephone Master Black Insert-BT Phone Socket, 240 V

The product was fine however no wiring instructions what so ever ,and the socket I was changing had A an B with a blue and a white wire going to them, two wires going to number 2 and 5 , the new just numbers 1 to 6 I google searched this and fond nothing only the fact your not allowed to tamper with the line coming to your property connected to A an B I connected A and B to 2 and 5 on the new socket got my phones working but hence no internet which is what the blue/white and white /blue must connect so took pot luck and connected these also to 2 and 5 which at first didnt work but then it did . Hope this is helpful to anyone with the same problem. It does now match the silver socket I have fitted next to it shame BT dont do a silver version of their master socket .

Happy with it. Looks great with my other brushed silver items in newly decorated room
